Malossi WingBell clutch bell for Gilera Runner 2-stroke maxi scooters
The Malossi Wing Bell undoubtedly belongs to the top class of clutch bells, here for Piaggio / Gilera / Aprilia 2-stroke maxi scooters. The bell can be used with all setups, from original to high-end, and is part of the Malossi Maxi Delta clutch kit for Piaggio 2T 125 - 150cc.
Malossi wingbell - Innovative cooling and HQ materials
The outstanding feature of the Wingbell is the welded-on outer ring with cooling fins. This cooling ring has two advantages - on one hand, the heat generated during clutching is effectively dissipated, and on the other hand, the clutch bell is reinforced and stabilized. The machined cutouts also contribute to cooling, but primarily serve to reduce weight.
Malossi uses only high-quality materials. Manufactured from forged special steel (39NiCrMo5) and finished with a nitride-hardened, rust-protected surface, the Wing Bell offers unsurpassed stability and durability.
Specifics Malossi Maxi Wingbell:
- Material: Forged special steel (39NiCrMo5)
- Diameter (inside): 134mm
- Compatibility: Gilera Runner 125 - 180 2T / Aprilia SR 125 - 150 2T / Italjet Dragster 125 - 180 2T / Piaggio Hexagon + Skipper 125 - 150 2T / Gilera Typhoon 125
The function of the clutch bell
Even though the clutch bells of scooters (centrifugal clutch) and clutch baskets of motorcycles (with multi-plate clutch) look different, their function is basically the same. What changes is the way they are actuated.
On a scooter or moped with a centrifugal clutch, when the engine revs up, the clutch shoes spread and engage the clutch bell and cause it to rotate. The bell then drives the transmission, which in turn turns the wheel.
On a motorcycle or motocross bike with a multi-plate oil bath clutch, the lined clutch plates engage the plain metal plates, which in turn drive the bell to rotate the transmission and wheel. When the clutch is actuated, the lined discs no longer engage the plain discs and rotation comes to a halt.
In short, the bell ensures that rotation is transferred from the engine to the gearbox and wheel.
Clutch bell: performance
With a tuning clutch bell, it is possible to improve performance or reliability.
Choosing materials like steel instead of aluminum provides greater durability. The heavier weight of steel also leads to higher inertia, which in turn can lead to higher torque. This is the case with the Hinson Momentum bell, for example.
A bell can also have cut-outs to improve cooling and thus prevent wear. Therefore, on scooters, you often find ventilated racing clutch bells. Also in motocross, some clutch bells have more cut-outs than others.
In summary, the weight and ventilation of a clutch bell affect the overall performance of the engine.
